This invention relates to a water'heater' and particularly to an improved heater wherein im roved electric.means are provided for eating the water immediately Another object of the invention is to providean electric water heater wherein a prssure actuated switch is provided and used to turn on the current immediately upon the rbefore'it vis discharged.

1o flowing of water through the heater.

A further object of the invention, more specificially, is to rovide a water heater wherein the iiow o? water into the heater turns on the current instead of the change of 15 temperat ure. An additional object is to provide a water heater wherein the water is caused to pass around thejacket before passing through the heater and in this way have the tempera- 20 ture thereof raised before entering the heat- 031e .a di.

The 'lisformedwithas'piralgroove-S inwhiclPlmsiicitin'gtl d to 'tth groove is eny ee permi e coil 9 to be without comthetubet. Apairof lead-in-wires 10' and 11 are rovided, one Awireextendingtooneendof coi18and theotherwiretothe undingthetubeisaheatingcoilm through a. m'table' sleeveor nipple 13 andisin any suitable manner `inthe tube 6, w block 7 of any" coil9 is mounted. Thevheater is in condition opposite end. Surwith' the valve or spigot air relief valve 15 extends through the casf 'ing 2 and into the inner casing 3 whereby from the top to"A the bottom of casing 3.

An opening 18 is provided in the section 16 near the top so that water from tle cham- ,ber or space 19 between the casings 2 and 3 may pass through opening 18 into the passage-way 17 thence into the inlet end 20 of the heating coil 12.

From Figure 1 it will be noted that the water enters the s a'ce or chamber 19 through pipe 21 an lpasses upwardly and finally through opening 18 and from this opening the water passesI downwardly throug the passage-way 17 and from thence through the heating coil 12 and nally out the discharge i 22 which is secured to the valve. 14.' e coil 12 at the entrance 20 is provided with an aperture 23 normally closed by the valve 24 which is secured to a pivotally mounted member 25 acting normally to cause the valve 24 vto close the may1 completely fill the inner casin 3, valve i 15 is allowed to remain open for t e escape Y of air until water begins to esca therefrom whereupon the same is clo and the for use. When the water in the inner casing 3 is heated, the saine will transmit heat tothe watering coil 12, which water may be drawn of from time time as desired. As the water in the becomes heated, it will expand somewhat. and this expansion is taken care of Aby thevent a rture 26. y

The water suppli to the chamber 19 is su plied through ppe 21 which is connectes to any suitab .sourceby pipe 27 inner casing water to pass from the interior of thereof a sufficient through the valve 28. In order to turn on the electricity and turn the same off automatically and at the proper time, the valve 28 is associated with certain switch mechanism interposed in the circuit of the lead-inwires 10 and 11. The valve 28 is provided with a rather large chamber 29 and a valve seat 30 which co-acts with a valve member 31 which is preferably hollow and in the.,

nature of a float so that it may be easily moved by the pressure of water.

This valve member is connected to a ball 32 accurately ground so as to lit into a valve seat 33. A member 34 acting as a bracket is screwed onto an extension of valve 28 and carries a plate 35 which is of glass or other insulating material and on which is mounted a covering 36 preferably of glass. A s ring contact 37 is connected to the plate y a screw 38, `which screw is also connected to the wire 39. The wire 39 is connected to' one side of the battery or other source of current 40, which battery has a wire 41 extending to the lead-in-wire 11. An arm 42 is connected with the ball 32 but is insulated therefrom by suitable insulation, said arm being formed with a metal u per end adapted to engage the spring 3 for closing the circuit of battery 40. A spring 43 is connected at -one end to the arm 42 and the other to bracket 44, which bracket is connected through wire 45 to the lead-in-wire 10. Normally, the spring 43 and associated parts assume the position shown in Figure 1 but when the valve 14 is turned and the Water begins to flow through the heater, the pressure of water against. the valve member 31 will swing the same to the dotted position shown in Figure 1 whereupon the water may freely pass into the heater and arm 42 brought over into contact with spring 37, thus closin the circuit of the heating coil 9. It wil thus be seen that the current is turned on immediately upon opening valve 14 and as soon as this valve is closed, the pressure against valve member 31 will cease so that spring 42 will immediately function for opening the circuit and moving valve member 31 to a closed position. It will be understood that the valve member 31 need not make a water tight connection with its seat and infact, may not touch the seat if desired but is merely positioned in the path of flow of water so as to be moved by the pressure distance for closing the circuit. The spring 43 is suiiciently strong to move the arm 42 away from spring 37 whenthere is no flow of water but immediately upon even a slight ilow of water the pressure will cause the arm to move over into contact whereby the current 'will be turned on to the heating coil.

What I claim is: 1. An lelectric heater,.comprising a heatheating element, a

.means for directing water into :said heat- -ing coil, a'valve memberinterposed in said means,v an electric switch connected with said valve member in such a manner as to be closed when the valve member is o n, a spring for o ening said switch an simultaneously clbsing said valve member, and means forming a circuit for said heating element, said means including a source of current and said switch.

2. An electric heater, comprising a heating coil, a container surrounding said coil, an electrical heating element arranged .within said coil, a water jacket surrounding and 'spaced from said container, means for directing water into the lower part of said water jacket, means for directing water from the upper part of said water jacket into said heating coil at the lower end thereof, and means for turning current onto and oi of said heating element.
